Title of Invention | BINDER FOR HIGH WET-STRENGTH SUBSTRATES |
---|---|
Abstract | The present invention is directde to a fibrous substant made of chemically bonded fiber. where t he fibers are bound with a polymeric binder in an amount which is sufficienl to bind the fibers together to form a self-sistamating web, and where the binder is charge rerizet as having a wel lersilc sturgth of greater than 4500 gram per inch (gfint) when measured at a 20 percent add-on on wherman #4 CHR chromartography paper which Is drum dried for90 seconds at 210 to 21515 'F and cured for 3 minutes at 300 to 325 "F. Perferable the levele of free formaldehydeIn in the fibrous substrate is less than 15 pprt.The curilsion binders of the invention may be used to bind fibers together into a substance roay be used to be used to bind pigment colors or other substantces to a substrate; may be used as a backing material may be used to finish Or surface-treat a substratc. Because of the high level ofcrosslinking,substracshound or treated with the emulsion polymer have excellentl wet strenglh and good durabitily weatherability and vater/solvent resistance |
